Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662844, here are decompositions:

13 + 8662831 = 8662844
37 + 8662807 = 8662844
61 + 8662783 = 8662844
97 + 8662747 = 8662844
313 + 8662531 = 8662844
373 + 8662471 = 8662844
397 + 8662447 = 8662844
433 + 8662411 = 8662844

Showing the first eight; more decompositions exist.
